How to Clean and Replace the Drain Valve

In this video, we'll walk you through how to clean and replace the drain valve on your Decent Espresso Machine.

You'll need to clean the valve if:

The drain valve remains open during shots.
The drain valve doesn't open when the shots end, causing pressure to stay trapped in the group head.

If cleaning or decalcifying doesn't resolve the issue, the valve will need to be replaced.
